troubleshooting - Why won't my computer boot (first time)?

My Parts:

• Motherboard ASUS Sabertooth Z170 S DDR4 LGA1151 ATX CPU


• Intel i7-6700k FC-LGA 14C 3.40GHz 8M Cache 4 LGA 1151 CPU Cooler


• Hyper 212 EVO RAM


• 16GB HyperX FURY PSU


• EVGA SuperNova 650Watt 80+ Gold rated Modular ATX 12Volt SSD


• 500GB Corsair Force LE OS


• Windows 10 Home


• Clean Install GPU


• Nvidia GTX 980

After putting together all of my components I tried booting my computer, and everything powered on correctly, but nothing displayed on the monitor. I would suspect a bad HDMI or Monitor, but it works perfectly with my current system that I was using 10 minutes before testing the new build.

So I thought it may be the PSU, but every fan was on, the motherboards Power light was on, but out of the 5 lights (DRAM,CPU,VGA,BOOT,PWR) it was the only one lit.

I am only trying to get to the BIOS screen to setup drivers, so I removed all unnecessary components, leaving only CPU, Power, Keyboard, RAM and HDMI plugged into the motherboard, but still nothing. All fans in the case are fully functioning, even the CPU fan, but it seems the computer is stuck between power on and Boot; I have no idea why.

I even tried to cycle the RAM cards through both channels, adjacent channels, one stick of RAM in each of the four slots by itself. Still nothing.

To reiterate, all peripherals and cables are fully functioning.

Hopefully this is enough information to get the problem across.

Is there anything else I can do to resolve this?

Answer

After cycling the sticks of ram, ensuring the CPU connectors were not obstructed by thermal paste, making sure the power was correctly connected to the CPU and Ribbon ports on the motherboard, using a jumper to flash the CMOS, removing the CMOS to reset BIOS, Removing the video card to connect video cable to the on-board video port, testing a secondary power supply to ensure original Power supply was not bad, testing monitor and video cable to make sure they are both good, and testing a new processor to make sure the processor was not dead-on-arrival we were able to determine the motherboard was faulty.

The motherboard was loaded with a corrupted BIOS, rendering it as a manufacturer's fault and was forced to be replaced/returned. There is no fix for this particular problem other than getting a replacement.

EDIT: It turns out the CPU was also DOA. After ordering a new CPU and Motherboard, the issue has been resolved.
